Abstract
It is said that an approach to environment problems is necessary to prevent the global warming. The correspondences of the global warming and the waste disposal are necessary for the machine tool as well. Carbon dioxide is said as the cause of No.1 of the global warming. It is necessary to saving energy for reduce the discharge of carbon dioxide. A machine tool uses a wide area when it is compared with a product. We researched the base technology, and developed a prototype of the small sized, low energy, multi spindle automatic lathe "ECOM". This machine occupied only 1/6 of floor space and power consumption was 1/3 in comparison with Tsugami automatic lathe.
